first embodiment
[0045]According to a body fluid suction reservoir of the present invention, as shown in FIG. 1, a fluid collecting port 5 is attached to pass through a bag 1, such that a drainage tube (not shown) kept in a patient is connected to the port 5. Preferably, the fluid collecting port 5 has a fluid collecting port one way valve 6 so that body fluid collected in the bag 1 does not flow back into a body cavity of the patient. In a similar manner, a fluid evacuate port 7 is provided to pass through the bag 1, and is provided with a lid 8 for the fluid evacuate port to be attached to the fluid evacuate port 7 during suction and collection (FIG. 3). Accordingly, when the suction and the collection are completed, the body fluid is evacuated by removing the fluid evacuate port lid 8 from the fluid evacuate port 7. As is understood from FIGS. 1 and 2, in a state before the suction and the collection of the body fluid, a spring 3, two plates (a first plate 11 and a second plate 12) holding the sp...
third embodiment
[0063]Thus, by constituting the first plate and the second plate by completely different components for each function, it is possible to constitute each part by a material suitable for each function, which makes it possible to broaden the width of material selection. That is, in the case of the third embodiment, since the springs 3 are supported by the core parts 42 and 44, it becomes possible that only the core parts 42 and 43 are constitute by a hard material.
second embodiment
[0064]Accordingly, similarly to the case of the second embodiment, it is preferable to use the engineering plastic such as polyacetal, filler reinforced plastic, fiber reinforced plastic and the like which have high elastic modulus and creep resistance, or metal such as aluminum or stainless steel as a material of the core parts 42 and 44, and to use plastic such as polyethylene or polypropylene having transparency and large breaking elongation as a material of the shell parts 41 and 43.
[0065]In the case of the third embodiment, since the core parts 42 and 43 support the springs 3, load in a direction vertical to surfaces of the plates does not directly act on the lock body 4 from the spring 3 and thus, it is possible to slide the lock body 4 on the second plate, smoother.
